Patented Oct. 28, 1952 DEVICE FOR WRAPPING HOLLOW PACKAGES 6 Henry J. McDermott, 'Collingdale, Pa.,' assignor to American Viscose Corporation, Wilmington, 'Del., a corporation of Delaware Application July 23, 1946, Serial No. 685,745

13 Claims.

This invention relates to modifications of a form of apparatus shown in my copending application Serial No. 568,462, filed December 16, 1944, now Patent No. 2,436,481, for applying a covering member to a hollow package.

The present invention is particularly useful for the application of a flexible protective covering member such as a knitted sleeve or even a paper sleeve to a hollow package of artificial filaments, such as a cake of rayon obtained by collection in a spinning. pot.

The present invention has as its principal object the provision of a simplified form of apparatus which is highly convenient to operate. Additional objects and advantages of the invention will be apparent from the drawing and the description thereof hereinafter;

In the drawing, which is illustrative of the invention- Figure 1 is an elevation in cross-section of a preferred embodiment,

Figure 1a is a perspective view of the packagereceiving bucket and package-engaging plate of Figure 1 with other parts generally removed,

Figure 2 is an elevation in cross-section or a modification, and a Figure 3 is a View taken on line III- 111 of Figure 2 showing a'latching construction.

In general, the device of the present invention comprises two concentric hollowed structures and a package-engaging or package-supporting memj b er or,plate adapted to fit between the two concentric structures. Relative movement is im-' parted to the package-engaging member and at least the outer of the concentric structures and advantageously, spring means normally urges the relative displacement of the member and outer structures to a condition in which the package engaging member is nearthe open end of the outer structure. Advantageously, latching means that relative position in which the package-engaging member, is well within the recess formed within the hollowed-out outer structure. Y

. As shown in Figures 1 and la, the device comprises suitable supporting means in the form of a hollow post 2 secured to the floor or other base by means of a flange 3. To the upper end of the post there is secured a bucket-shaped structure 4 having an upwardly extending sleeve-like portion 5 with a hollow interior. concentrically within the sleeve of the bucketstructure. there is disposed an inner structure comprising a cupshapedel'ement 6 having a recess ladapted to receive'one end of a flexible wrapping member with one end of the sleeve tucked within the may be provided to retain the various parts in 8. The concentric structures are open .at the upper ends and in the recess between the sleeves of the inner and outer structures, a plate 9 for engaging one end of the package (and, when the device is in the-vertical position shown, for supporting the package) is carried, such as by means of a plurality of rods l0. These rods to extend slidably through openings H in the outer structure and are turned inwardly to a supporting block or hub [2 carried upon a hollow shaft (l3 and slidable within the hollow post 2. A spring l4 normally urges the member 9 into the position shown in Figure l, a central rod I5 within the spring tending to guide the spring intoethe hollow shaft l3. A collar 16 secured to the shaft 13 has n a projection Il extending through an axial slot I8 in the lower end of the post 2.- The projection I 1 serves as a foot lever to facilitate the manipulation of the device.- Adjacent the lower end of the slot l8, a latch I9 is provided (see Figure 3).

This latch is counterweighted' at No so that it normally rests in the position shown, the cam surface l9b serving to be engaged by the foot lever l1 so that such lever can pass into the latching position shown in F'igure 3, and this latch may be rocked out of locking position over the projection H as shown in Figure 3 by means of the foot crank lever 26 whose pivotal shaft 2| extends through a bearing ina block 22 to a point of securement with the latch l9. v

'In operating the embodiment ofFigures 1 and 6 1a, a flexible sleeve-like cover 8is placed upon the upper end of the device as shown in Figure 1 recess 1 of the cup-like element 6 and with the other end of the cover turned back'over the outer'sleeve 5. The hollow package 'P,-such;as-a wound cake of rayon, is then placed upon'ythe portion of thecover resting over themember 9. The operator then presses the package downwardly with thetpalms of .his hands until he can engage the projection I! with the latch 19., this corresponding preferably to a condition in which the package is completely withdrawn intolthe recess between the inner and outer structures. During such downward movement of the'package, the covering 8 is applied to both inside; and outside surfaces of the hollow package Att-he conclusion of the downward movement of the package, itis only necessary forthe operator to withdraw the remainderof the end of the cover tucked within the recess 1 and'extendittover the topend of the package and partlyfoventhe upper end of the outer sleeve 5. Preferably; sufli: cient of one end of the cover is .tucked' into-the cup-like element 6 so that at the final step the cover overlaps the upper portion of the outer surface of the outer periphery of the package as well as the top end surface and so that the other end of the cover previously disposed outside the outer structure is insufficient to reach the top of the package. This assures that the cover will not pull away from the top end surface of the package.

The package may then be ejected from the sleeve and this may be accomplished either by releasing the projection I! from the latch l9 so that the spring l4 lifts the package upwardly or by the insertion of the fingers through the axially directed slots 23 in sleeve 5 and radial slots 23a in the plate 9 and then lifting the package with the fingers. See Figure 1a especially. While slots 23 may extend clear through the upper rim of the bucket 5, it is preferable to avoid the break in the rim by terminating the upper ends of the slots as shown in Figure la so that a smooth rim is provided for engaging the cover or wrapper. When the slots extend through the upper rims of sleeve 5, their lower ends may reach only part way to the bottom of the sleeve 5 and the element 6 may be provided with aligned slots of the same length (as shown in Figure 2) to permit seizing of the package by fingers reaching through the slots around the upper end of the package. Preferably, however, the slots extend to the bottom of sleeve 5 and partway inward along the bottom (as shown in Figures 1 and 1a) in alignment with slots 23a in the plate 9.

As the package moves upwardly during ejection, the portion of the wrapper covering the top end of the package and extending over the upper end of sleeve 5 slides off the sleeve 5 and grips the upper end of the outer periphery of the package, overlapping the other end of the cover previously applied during the downward movement of the package into the recess within the sleeve 5.

Figure 2 illustrates a modification in which such of the parts as correspond substantially to the parts in Figure 1 are given corresponding numbers. The supporting post 2 secured to a floor or other base by means of a flange 3 carries in relative fixed relationship thereto the bucketli-ke Structure 4 having the outer sleeve 5 in which notches or slots 23b may be provided if desired. A shaft 24 is axially slidable within a bore through the central hub of the bucket-like structure 4 and carries at its upper end the packageengaging member 9a which in this instance is a plate having an outer free annular portion adapted to receive the end of the cake. To the top of the plate is secured the cup-like or sleevelike inner structure 6 having the hollow recess 1 adapted to receive one end of the cover 8. The structure 6 may have notches or slots 23c aligned with slots 23b and extending to approximately the same depth from the upper rim of the structure 6 as slots 23?) do from the upper rim of sleeve 5. If desired these slots may be replaced by the slot system 23 and 23a of Figures 1 and 1a.

The shaft 24 is secured to an intermediate 'slid ing block 25 from which depends the hollow shaft l3 containing the spring [4 and carrying the collar IS with its projecting member H. A rod I5 is provided as in Figure l and the latching system comprising latch 19 and crank lever 28 is identical to that shown in Figure 1.

In this embodiment, the member 9a is initially in an upper position adjacent the open end of the sleeve 5. The cover 8 is placed about the inner structure 6 with a portion of one end tucked into the recess 1 and the other end being overlapped about the sleeve 5. The cake is inserted over the cover carried by the inner concentric structure 3 and brought to rest upon the portion of the cover carried by the annular free portion of the member 9a. Then the package is moved downwardly into the recess within the sleeve 5, such movement sliding the outer end of the cover from about the sleeve 5 into engagement with the outer periphery of the package. The position thus reached is shown in Figure 2 and it is only necessary for the operator to withdraw the end of the cover tucked in recess 1 and spread it over the top end of the outer structure and thereafter to remove the package from the outer structure. This removal may be accomplished either by insertion of the fingers through notches 23 and lifting the cake from the member 9a or by releasing the projection l1 from latch 19 and allowing the spring M to lift the inside assembly with the package to its upper position.

Both embodiments shown and described herein are adapted to rapid manipulation. The fatigue of the operators is greatly reduced by the provision of the spring means M, which eliminates the lifting of the package-supporting structure. Of the two embodiments, Figure 1 is preferred, since it is somewhat easier for an operator to place the package in position without mussing up the internal windings which may occur if insufficient care is taken in placing a package about the inner structure 6 of Figure 2.

It is to be understood that changes and variations may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
